last should start with mLogElements.end() and be updated as
we iterate to find a matching time entry in the list. Since
it is impossible(sic) for a newer start time to be supplied
than the list, the incorrect iterator initialization should
be inconsequential, but if it ever happens this change will
behave correctly and dump nothing.

Add support of multiple class names in service, so that related services
can be grouped together. By doing this, we can start/stop some services
for special purpose. For example, early zygote, early boot animation
and etc.

- Use ro.build.shutdown_timeout to cover the total time for shutdown.
Limit wait time for termination only to half of shutdown_timeout
with max of 3 secs as process not terminating by that time
will not terminate anyway. It is better to move to the next
stage quickly. fsck time for user shutdown is excluded from timeout.
- Change last detach to kill, sync, and umount. Last detach did not
work in many tests.
- add sync after emulated partitions umount as it can trigger
change in /data.

A mixture of fixes and cleanup for LogKlog.cpp and friends.
- sscanf calls strlen. Check if the string is missing a nul
terminator, if it is, do not call sscanf.
- replace NULL with nullptr for stronger typechecking.
- pass by reference for simpler code.
- Use ssize_t where possible to check for negative values.
- fix FastCmp to add some validity checking since ASAN reports that
callers are not making sure pre-conditions are met.
- add fasticmp templates for completeness.
- if the buffer is too small to contain a meaningful time, do not
call down to log_time::strptime() because it does not limit its
accesses to the buffer boundaries, instead stopping at a
terminating nul or invalid match.
- move strnstr to LogUtils.h, drop size checking of needle and
clearly report the list of needles used with android::strnstr
- replace 'sizeof(static const char[]) - 1' with strlen.

For logd daemon, heavy reader stress. For system popen fork and
execute of logcat measure baseline against liblogcat. For liblogcat
local concurrent thread, locking, argument parsing and context scaling
for popen-style pair of android_logcat_run_command_thread* functions.
NB: 1000 logcat executables ran, but did not scale well on time
blocked for more than a minute. With 343 contexts of
android_logcat_run_command_thread ran out of local resources
to even return a file descriptor, and the per-context event tag
mappings coincidentally ran out at 340 when threads ran, although
that path was consistently 15% faster than the popen test.

After removing bg_non_interactive cgroup, there is only a ROOT cgroup.
This CL removes the no-op trying to set cgroup.
It also removes the attempt to open non-exist bg_non_interactive cgroup.

Test: marlin boosts and cgroup ROOT task looks normal
